Unable to save level with Procedural Mesh

Development Programming & Scripting
1

Preview of 4.8 has been released couple of weeks ago and I ran into a problem with testing new Procedural Mesh system.

When I add Procedural Mesh Component into my BP (doesn’t matter, if I do it manually or dynamically using Add Component function in Construction Script)and add BP to my level, then I’m not able to save the level anymore.

This is the error, that appears on level save:

It only can be saved after I remove Blueprint from level.

Another bug is about geomentry.

It crashes the editor on Build Geometry, when Procedural Mesh has actual geometry in it (If it doesn’t, build goes well)

Hi AlFlakky,

Are you referring to the Procedural Foliage System? If so, please let me know what your settings you are using for the foliage system are. Additionally, Please make a second answerhub post about the Build Geometry crash. This makes it easier for us to focus on individual bugs so we can quickly address them and so other developers who may be experiencing the same error can comment with potentially helpful information related to the specific bug. Thank you!

No. I’m about the new feature, that allows you to build geometry (3D models) using blueprints.

Here is what I mean: Spline-based mesh generation - Community & Industry Discussion - Unreal Engine Forums

I’m making this asset for everyone, but the problem is that it cannot be saved while on level.

Does this occur in a clean, blank project with no additional content?

Yes. I made blank (without Starter Content) 4.8 project and add there this BP with Procedural Mesh Component.

Can you give me a list of steps that you are taking that consistently reproduce this error so I can try to reproduce it on my end?

Looks like it is fixed in 4.8 Preview 3
